Exhibition... a special fetish

I have a particular interest in men who display themselves in public, even busy, places. I am fully aware that this kind of act is reprehensible but since it is clearly a fetish, I am always looking for images or videos of this type.
What I particularly like are guys masturbating on buses, or trains, or even in a taxi. Seeing a man holding his cock as close as possible to another person without the latter suspecting anything excites me a lot. I guess I wouldn't have the courage to do it myself. My boldest experience has been driving on the highway with my trousers down for a long drive. I held my tail in my hand, stroking myself, but still when I was in a situation where I could be seen I preferred to hide my sex with my hand or my T-shirt.
Sometimes some guys go so far as to ejaculate in the public place, I love to see that. I also like it when they piss on a train or bus and if they have a firm erection while they are urinating it arouses another special interest, another fetish: seeing a guy pissing while he has a hard-on.
Strangely enough I am less sensitive to women's exhibitions in public places. Maybe because it's more "common".
I'll probably talk about it again soon, because it really turns me on.
